A DOS is assayed by a person, the DOS attack essayed by apportioned persons, is called Distributed Denial Of Service (DDOS). This paper evinces, the DDOS attack architecture, DDOS attack types, DDOS attack tools, and DDoS attack defence mechanisms. This paper, essentially unveils the DDoS attack defence, based on location posit and on activity deployment. This paper presents the boon and bane, of the different DDoS defence mechanisms. The desired objective of this paper, is to sort and properly organize the attacks and existing mechanisms, in codified order, for a better know-how and understanding, of DDOS attacks. Keywords: Denial Of Service; Distributed Denial Of Service; DDOS tools; DDOS Defence. 1 3423 International Journal of Pure and Applied Mathematics Special Issue 1 INTRODUCTION Networks attacks, repudiate the access of computer network resources by using malignant node, known as availability based network attacks. Denial Of Service(DOS)[1][5][23], is sort of an active information security attack, which is an emphatic trial to squander the victim resources, like a machine or network resource provisionally or perpetually, for legitimate users by an enormous amount of pernicious packets which are sent from a single machine.
